All I can say is - God must think I am a VERY tough cookie!
For me, my philosophy is that life's often hard, for most if not all people. We all have crosses to bear.
I am thankful, despite all the set backs and body blows, I am still carrying mine. Our strength and our attitude gets us through if we are lucky. Some fall along the way and find getting back up a real struggle.
When I told my neighbour (a while ago when one bad time followed another really bad time) that God might be testing me by giving me one heartbreaking trial after another, on top of all the family responsibility and caring I'd had to shoulder alone, she accused me of "letting the Devil in!"
I was quite taken aback and insulted. I like to think we have a higher power who doesn't mind us questioning our lives and sometimes asking "What's it all about?"
I think I am blessed to have strength and determination, despite a fairly dodgy body full of weaknesses and ailments of various sorts. I also look for silver linings in most clouds, if I possibly can, although there have been a few big ones which darkened my world for a long, long time, until the pain of it all eased a little.
"This too shall pass" is a phrase that keeps me going.
